Door wiring looms

[Bogsye]

One of the troublesome areas on my car has always been the door electrics and window drop. Intermittent operation of the buttons and the window drop.
I've been through all the great threads on here and have put superseal connectors on, which made an improvement, but we seem to be back at the start again. My thought is that he loom might be damaged at the door hinge area.

As a little winter project I've decided to make up a couple of new looms. The cerbera site usefully has the door and door trim loom diagrams detailling wiring colours and cross-sectional areas, etc.. I thought I'd just buy single colour wire and put coloured wire markers on the ends.

Has anyone else done this, and have any experince they would like to share?

Thanks,
Brian

Upping the size of cables will help much

Hi Brian,

Not done this on the doors but I have had repeated problems with my engine loom, I guess they are starting to show age.

I decided to use this as an opportunity to update the ECU for a new MBE A9B units with dual maps, wide band lambda's and knock control.

Currently in the process of fitting it all which should get finished next week. Wiring loom had to be made from scratch all the correct wire colours were used so future fault tracing will be easier, if you label the ends of each wire but use one wire colour for all wires how do you easily find it at the mid point?

Thanks PS for the pointer to the window circuits - I'll read that up and get my head around that.

Good point Gruffalo regards wire colours. I should really calculate up what the likely cost would be to replicate the wire colourings properly. Sounds like it's time for a spreadsheet!!

Thanks again

Ok then

As gruffalo comments, coloured cables is the best way

Take a look here Thin Wall Cable

and

Here Standard PVC Cable

It can be seen that thin wall cable is close to half the size of standard PVC cable when of a similar current rating, works well especially when needing room to get cables into doors

Thanks for the links.

I noticed the thin wall cable and wondered if that was a good option? There was also tinned cable for more aggressive environments which might be useful, but then I guess I’ll be tinning the wire ends anyway.
